Objective:To investigate the effect of Sec-O-Glucosylhamaudol on inflammatory mediator and cytokine( NO and IL-6)production in Lipopolysaccharide(LPS) stimulated murine macrophage(RAW264.7).Methods: Macrophages were induced with LPS,and incubated with different concentrations of Sec-O-Glucosylhamaudol(20,40,80 μg/ml),the quantity of NO production was measured by Griess reagent;the IL-6 production were measured by enzyme linked immunosorbent assay(ELISA),the expression of nitric oxide synthase( iNOS) in cells were detected by Western blot;the expression of iNOS and IL-6 mRNA were analyzed by real-time PCR.Results:Each concentrations of Sec-O-Glucosylhamaudol(20,40,80 μg/ml) inhibited the production of NO and IL-6 in LPS-stimulated RAW264.7 cells(P<0.01).This compound also reduced the mRNA expression of iNOS and IL-6.Conclusion:Sec-O-Glu-cosylhamaudol exhibited anti-inflammatory activity by inhibited the NO and IL-6 production in LPS stimulated RAW264.7 cells.

Objective: To establish human multidrug-resistant hepatocellular carcinoma cell line(QGY7703/DDP) to analyze its different resistance and sensitivity. Methods: The human hepatocellular carcinoma cell line QGY7703 was continuously grown in the presence of cisplatin（DDP) for up to 6 months. Cell proliferation and cytotoxicity were serially monitored. Results: The chemosensitivities to 5-FU，DDP，adramycin (ADM) and mitomycin(MMC) were different between QGY7703 and QGY7703/DDP. The exhibitions were 1.533 fold to 5－FU，2.181 fold to DDP，7.08 fold to ADM, 9.461 fold to MMC in QGY7703/DDP. Conclusion: The drug resistance in cancer cell lines can be established by exposing to antitumor drugs in cell culture system.

BACKGROUND:In recent years, many scholars adopted a joint non-fusion and fusion spinal fixation for multisegmental cervical spondylotic myelopathy, and achieved good clinical results. However, long-term clinical efficacy and possible related complications also require long-term fol ow-up of more in-depth study.
OBJECTIVE:To review the research and application progress of anterior fusion and non-fusion fixation surgical operation for cervical myelopathy.
METHODS:Computer-based search was conducted in China Journal Ful-text Database and PubMed database by the first author for articles related to anterior fusion and non-fusion fixation surgical operation for cervical myelopathy published between January 2004 and January 2014. The key words were“implant material;cervical spondylotic myelopathy;anterior;surgery;fusion;non-fusion;progress;hybrid;summary”in Chinese and“implant material;cervical spondylotic myelopathy;anterior;surgery/operation;fusion;non-fusion;research progress;hybrid;summary”in English. Final y, 35 articles were included for review.
RESULTS AND CONCLUSION:Fusion and non-fusion fixation methods for cervical spondylotic myelopathy had their own advantages. From the view point of indications, the non-fusion fixation was relatively limited. Currently, the fusion fixation was stil the main method in treatment of cervical myelopathy. Non-fusion method as an emerging fixation method also achieved good short-period results, but it needs a long fol ow-up study. Hybrid fixation integrates the advantages of both methods, and can reduce the pressure. Simultaneously, Hybrid fixation also can reduce fusion segments, and retain the range-of-motion of the cervical spine as much as possible. Hybrid fixation becomes a hot topic in recent studies. However, most current researches on Hybrid fixation are retrospective study, lack of control. The overal fol ow-up time is short. Thus, Hybrid fixation needs to be researched more deeply.

Translational medicine appears as a new branch of medicine, aiming at quickly transforming the basic research products into clinical application. Nowadays there is a trend that laboratory researches do not have a close relationship with clinical reality, which is facing the present medical research and education field. Herein translational medicine appeared to solve this fundamental conflict.In this paper, we will analyze the essence and status quo of translational medicine, and provide suggestion on the development of translational medicine from the perspective of medical research management.

Objective To explore the correlation between BCL2 binding component 3 (BBC3) expression and postoperative survival time of lung squamous cell carcinoma (LUSC),and investigate its molecular mechanism.Methods The expression of BBC3 in 39 patients was detected by using qRT-PCR assay.Meanwhile,clinical data of all patients were collected by follow-up visit.Then,the survival analysis was performed by using Kaplan-Meier and log rank tests.Moreover,multiple factors analysis was performed using COX proportional hazard model.At last,BBC3 was over-expressed in NCI-H226 cell lines,then detected the effects of BBC3 expression on cell proliferation and apoptosis by using MTT assay and flow cytometry.Results BBC3 expression were significantly correlated with the tumor metastasis (r=0.556,P=0.023),tumor size (r=0.532,P =0.042),T staging (r =0.551,P=0.021) and TNM staging (r=0.524,P=0.047).Meanwhile,the results of Kaplan-Meier and log rank tests found that BBC3 expression was significantly correlated with survival time of patients with LUSC,and the length of survival time in patients with high BBC3 expression was longer than that in patients with low BBC3 expression (x2 =7.542,P=0.006).The COX proportional hazard model indicated that tumor metastasis,T staging,TNM staging and BBC3 expression were independent factors which significantly affected survival time.Moreover,the proportion of apoptotic cells in the recombinant plasmid BBCs group was higher than that in the empty plasmid group and control group (P＜0.05).Conclusion BBC3 expression could suppress the proliferation of tumor cells and promote apoptosis,and are significantly correlated with survival time of patients,so which may be assistant biomarkers for prognosis of LUSC.

This review is intended to present the latest information on the pathogenesis of diabetic nephropathy based on the studies of recent years,involving potential therapeutic targets of diabetic nephropathy,such as hemodynamic dysfunctions,advanced glycation end-product,lipid metabolism disorders,inflammatory cytokines,and oxidative stress. Further studies are mandatory to investigate the effect of various interventions that modulate the pathogenesis in the treatment of diabetic nephropathy.

?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.

Objective To explore the change of perioperative serum alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) in patients with primary liver cancer undertaken transcatbeter arterial chemoembolization (TACE).Methods One hundred and two patients with primary liver cancer were performed with TACE treatment.The levels of AFP and CEA after treatment 3 d,1 week,3 weeks were detected and compared.Results The levels of AFP after treatment 3 d and 1 week were higher than that before treatment,but there was no significant difference [(549 ±30),(530 ±30) μg/L vs. (527 ±40) μg/L] (P ＞ 0.05).After treatment 3 weeks,the levels of AFP significantly decreased than that before treatment [ (351 ± 20) μ g/L vs.(527 ± 40) μ g/L ] (P ＜ 0.05 ).The levels of CEA after treatment 3 d,1 week,3 weeks were significantly lower than that before treatment [(410 ± 15),(350 ± 20),(200 ± 10) μg/L vs.(570 ±22) μ g/L] (P ＜0.05).After treatment 3 weeks,the levels of AFP and CEA achieved normal.Conclusions TACE in treatment for primary liver cancer can achieve better therapeutic effect,significantly improve the symptoms,decrease the levels of AFP and CEA.To control the indication and contraindication,perform TACE in time can decrease mortality,improve prognosis,and is valuable in clinic.
